This study aims to analyze the causality relationship between sectoral stock markets (agricultural, financial, industrial, and mining sectors) and economic growth in the short and long term as well as to analyze whether it has similar types or not. The data used is quarterly time-series data (first quarter 2009 to fourth 2019). To determine the causality relationship, this study conducts a variable and multivariate causality test. The results of the varying granger causality test show that there is only a one-way relationship, where the economic growth of the agriculture sector affects its shares. A one-way relationship also occurs in stocks of the industrial sector, which has an influence on economic growth. The multivariate causality test shows that the economic growth of the agricultural sector has a two-way causality relationship, and it also exists between the industrial sector and the financial sector stock markets. The two-way causality relationship between the stock market and sectoral economic growth is a convergence towards long-term equilibrium. The findings of this study suggest that the government through the Financial Services Authority and the Indonesia Stock Exchange have to maintain stability in the stock market as a supporter of the national economy.

This study investigates the adoption and application of digital transformation in the financial sector and analyzes the process and outcomes of digitization and digitalization in the field of the finance industry of South Korea and overseas, in order to seek both managerial and strategic implications for successful implementation of digital transformation in the future. The findings show that, for successful digital transformation, it is necessary to maximize active and systematic use of advanced online and digital technologies that form the basis of business and create an open, horizontal organizational culture and communication system to equally share and distribute advanced technologies and competencies through the entire organization. Furthermore, this study also discovers the legitimacy to concentrate the organizational competencies and know-how in providing technical training for members, expanding customer experience, and improving customer satisfaction services to contribute to improving the quality of life for members of the organization and creating and improving social and public infrastructures, instead of using digital transformation only to improve productivity of organizations or firms. As such, it is necessary to concentrate corporate competencies in establishing and supplying digital transformation that is not just human-centered but also has productivity, innovativeness, and reliability at the same time.

Debt and credit problems in Korea have been escalated during the past decade. The number of people with debt and credit problems is in its historic high. In May 2008, about 2.48 million debtors are officially classified as bad debtors and 7.20 million people have low credit scores. People with low credit scores are in disadvantageous situation in the financial market thus their financial transactions and activities are limited. In 2004, Korean government introduced various credit rehabilitation programs. However, most of these problems are remedial in nature and preventive programs such as credit counseling and debtor education are lacking. The purpose of this review is to examine US credit counseling and debtor education programs to obtain insights for preventive credit program developments in Korea. The review focused on programs offered through National Foundation for Credit Counseling, Jump Start, and Cooperative Extension Services from two large land grant Universities. From the program review suggestions and recommendations for educational contents, program and educator developments, and program quality control were discussed.

In dynamic management environment, CEO must make an efficient decision with information & knowledge management systems based on IT(Information Technology). As a key component to cope with this current, we suggest the business performance analysis system based on KDD(Knowledge Discovery in Databases). We consider the theoretical model that is composited both Value-Added in respect of stakeholder and Economic Value-Added in respect of shareholder. Additionally we use DBMS and data mining method using Genetic Algorithms as physical model. To demonstrate the performance of the business performance analysis system, we analyse a domestic motors industry. The empirical case is based on the financial data of KISFAS(Korea Investors Services Financial Analysis System) database. The samples included in the study consist of H motors/S motors industry over the 16-year from 1981 to 1996.

As financial transactions using mobile devices have been activated, mobile payment services have appeared and many changes have been made to the existing financial service methods. Due to the simplified payment method of mobile payment service, security threats such as personal information leakage, phishing damage, and malicious code are increasing. Research that can solve this is needed. In this paper, we discuss the features and security factors of mobile payment system. In order to improve the security of mobile payment system, we propose a fault analysis method based on frequency of occurrence using Fault Fishbone Analysis(FFA) technique.

We suggest a Business Performance Information System with Knowledge Discovery in Databases(KDD) as a key component of integrated information and knowledge management system. The proposed system measures business performance by considering both VA(Value-Added), which represents stakeholder's point of view and EVA(Economic Value-Added), which represents shareholder's point of view. In modeling of Business Performance Information System, we apply the following KDD processes : Data Warehouse for consistent management of a performance data, On-Line Analytic Processing(OLAP) for multidimensional analysis, Genetic Algorithms for exploring and finding dominant managing factors and Analytic Hierarchy Process(AHP) for applying expert's knowledge and experience. To demonstrate the performance of the system, we conducted a case study using financial data of Korean automobile industry over 16 years from 1981 to 1996, which is taken from database of KISFAS(Korea Investors Services Financial Analysis System).

Product factory is a real-time financial product design system for the Internet customers. Recently, as the number of the Internet customers increases, the importance of the product factory becomes more emphasized. However, there is not much research performed regarding its definition, properties, requirements, nor implementation. In this research, we make a clear definition of product factory, and analyze the requirements of the system from the perspectives of functions and services, and we propose an architecture that reflects the analyzed requirements. In additions, we implemented a prototypical system based on the proposed architecture to prove the usefulness of this research.

Objectives : This study investigates the determinants of contingent workers' ratio in public health centers. Since the economic crisis in 1997, there have been many studies on contingent workers in Korea. But, previous studies have been not conducted focusing on public health center. Methods : This study used 253 public health centers, installed and operated since December 31, 2008. in Korea as units of analysis. To examine the determinants of contingent workers' ratio, this study uses Pearson correlation and multiple regression analysis. Results : The following appeared as significant variable affecting contingent workers' ratio in public health centers; degree of the local government's financial independence(p<0.001), rate of increase/decrease in ages 65 and over(p<0.001), rate of increase/decrease in basic livelihood security recipients(p<0.01) and rate of increase/decrease in registered disabled persons(p<0.01). In contrast, internal organizational environment characteristics related variables were not statistically significant. Conclusions : Contingent workers' ratio in public health center is significantly affected by financial vulnerability of the local government and increase in demand of health care services.

The purpose of this study is to verify whether the technology grade, which is the result of technology appraisal by Technology Credit Bureau, can be extended and applied to the venture certification system. We confirmed that there was a significant difference in the average financial performance for three years after the certification and appraisal of the two groups after matching the venture certification enterprise group and the technology appraisal enterprise group in 2015 through the propensity score matching method. As a result, there was no significant difference in the financial performance of venture certified firms and technology appraisal firms, so we confirmed that the technology grade can be expanded and applied to the venture certification system. As a result of estimating the technology grade conforming to the venture certification system, it was concluded that technology outstanding firm(T1-T4) is a technology grade suitable for the venture certification system.
